SYRINGE Specification of Letters Patent.

Patented Nov. 2e, 19o7.

Application filed February 4.1907. Serial No. 355617.

To all whom it may concern:

Be it known that I, ARTHUR E. BoNn-' STEEL, a citizen of the United States of America, residing at Denver, in the county of Denver and fitate of Colorado, have invented .certain new and useful Improvementsin Syringes, of which the following is such a' full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in syringes and seeks particularly to improve the construction and increase the efiiciency of the syringe shown in the Patent No. 688,099, granted to me September 24, 1901.

The present invention consists in certain .novel features of thedevice illustrated in the accompanying drawings as will be hereinafter first fully described and then particularly pointed out in the claim.

In thedrawings, Figure 1 is a longitudinal sectional view of a syringe embodying the present improvement, and Fig. 2 is a similar view showing a modification.

The nozzle, 1, is fitted in the end of the usual bulbed tube which is not shown in the present instance as it forms no part of the invention. Fitted loosely on the nozzle is a sleeve or collar, 2, which is provided with external threads at one end and has the expansible arms, 3, secured to its other end. These arms extend outward from the collar and have their outer ends doubled inward on themselves as shown in my former patent, a spherical guard, 4, being secured to the extremities of said inwardly-turned ends. A small red, 5, is secured to the said guard and extends therefrom into the mouth of the nozzle where it is secured, the guard beingthus connected to the nozzle so as to always I be directly in alinement with the same and at a fixed distance therefrom. Mounted on the threaded end of the sleeve 2 is a nut, 6, which engages an annular groove, 7, on the rear enlarged portion of the nozzle so that when the nut is turned the sleeve will be caused to move longitudinally of the nozzle and thereby expand the arms as will be readily understood.

In the modified construction shown in Fig. 2, the connecting rod 5 is passed diametrically through the guard and its ends are then bent back to the nozzle and secured to the outer side of the same. This arrange ment is a cheaper construction than that shown in Fig. 1 and leaves the passage of the nozzle entirely unobstructed and may be preferred in many cases.

The operation of the syringe will be readily understood. After insertion in the vagina, the nut 6 is rotated so as to cause a longitudinal movement of the sleeve which in turns causes an expansion of the arms inasmuch as the guard is connected immovably to the nozzle and the ends of the arms are fixed to the guard. The resent construction maintains the guard 1n afixed relation to the nozzle directly in line with the mouth thereof so that an eificient spraying and scattering of the medicine is accomplished.'

Furthermore, the arms are held positively in their expanded positions so that there is no premature collapsing of the same.

Having thus described my invention, what I claim and desire to secure by Letters- Patent is A vaginal syringe consisting of a nozzle, a sleeve mounted thereon, means for causing the sleeve to move longitudinally upon the nozzle, a plurality of expansible arms secured to the sleeve, extending beyond the end of the nozzle and having their outer ends doubled inward on themselves, a spherical guard secured to the said inwardlyturned ends of the expansible arms in axial alinement with the nozzle, and a connectingrod having its opposite ends fixedly secured to the end of the nozzle and to the guard whereby the guard will be held permanently in axial alinement with the nozzle and at a fixed distance therefrom.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

ARTHUR E. BONESTEEL.
